Zebra_Database is an advanced, compact (one-file only), lightweight, object-oriented MySQL database wrapper built upon PHP’s MySQL extension. It provides methods for interacting with MySQL databases that are more powerful and intuitive to use than PHP’s default ones. It supports transactions and provides ways for caching query results either by saving cached data on the disk, or by using memcache.The class provides a comprehensive debugging interface with detailed information about the executed queries: execution time, returned/affected rows, excerpts of the found rows, error messages, etc. It also automatically EXPLAIN‘s each SELECT query (so you don’t miss those keys again). It encourages developers to write maintainable code and provides a better default security layer by automatically escaping strings. Zebra_Database‘s code is heavily commented and generates no warnings, errors, or notices when PHP’s error reporting level is set to E_ALL.

MADAL is an AJAX based database access layer for MySQL written in PHP and Javascript. It generates PHP and JavaScript/jQuery source code that is well documented, so you can use your IDE's auto-completion against database tables and fields. The documentation was designed with PHP Eclipse in mind, but should work for any IDE that recognizes PHP doc. It generates a set of PHP classes that mirror your database schema. It generates a set of JavaScript/jQuery classes allowing for simple client side display and modification. It generates an easy-to-use Web-service for accessing your database. An AJAX enabled field can be produced simply by printing the input field. Input fields are validated for their type. MADAL includes the whole set of default jQuery UI themes for styling of your pages.

DBPersister (database persistent library) is a PHP library which helps you simply and clearly use your database, taking advantage of powerful object oriented programming. You can use DBPersister to manage data from your database to your application. You can do all the boring operations (like loading a single record, saving a single record (insert, update, replace), and deleting a single record) without writing SQL code.

h2H Messenger is a secure messenger client that uses PHP OpenSSL functions, mcrypt, and PHPSecLib to encrypt messages at-rest using RSA keys. The user only creates an account and the application handles the public key generation, key management, key exchange, and encryption and decryption of messages. There are no algorithms or key sizes to choose. It uses strong standards (AES 256, 4096 bit RSA Keys, SHA1, SHA512, etc.) in the background, and requires two-factor authentication using a code sent via SMS or using Asterisk.
